Encalypta ciliata, also known as extinguisher moss, is a plant belonging to the genus Encalypta. These plants typically grow in large tufts on limestone rocks, ledges, and walls. Approximately 8 of the 34 species in this genus are native to North America.1

Extinguisher moss plants are usually between 1 to 3 cm tall. They feature erect capsules, which are spore cases, supported by stalks about 5 to 10 mm long.
